Figure 10-16. Connections on the Main Distribution Board.
J31 and J32 connect to the spare card slots, in case logic cards are
installed in the spare slots or are moved to the spare slots. J33 through
J42 are not currently used.
Switch one located at S1 on the distribution board must be set to ON for
systems configured with standby redundancy. The remaining switches
should be set to OFF. For systems that do not have standby redundancy,
set all the switches at S1 to OFF.
The system hardware configuration is set by 10 dip switches located at S2
on the distribution board. These switches indicate to the monitor card
which alarm status lines are active and should be monitored. The switches
are set at the factory and do not need to be changed unless the system is
reconfigured later. Table 10-9 provides a description of each hardware-
configuration switch. An ON setting on the S2 switch indicates that the
switch is disabled.
The monitor card must be reset and restarted after the hardware configuration
is changed. When the system power is turned on again and the system is re-
booted, the monitor card is automatically updated.
Voltage test points for +5 Vdc and +12 Vdc are located in the lower right
portion of the distribution board. Refer to Figure 10-16 for the exact location.
The test points are TP1 (return), TP2 (+5 Vdc), and TP3 (+12 Vdc).
A second set of test points is located at the lower middle of the board, for a
second XC1000 cabinet, if installed. These test points are labeled TP6
(return), TP7 (+5 Vdc), and TP8 (+12 Vdc).
